g A test was conducted to determine if there is a difference between Canadian and American average heart rates. A group of 36 Ca

melisa1 [442]

Answer:

The test statistic | t | =4.45

Step-by-step explanation:

Step(i):-

Given that the first sample size n₁ = 36

Given that the second sample size n₂ = 34

Mean of the first sample x₁⁻ = 68.5

Mean of the second sample x₂⁻ = 70

Step(ii):-

Test statistic

$t = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} } } )}$

$t = \frac{68.5-70}{\sqrt{2(\frac{1}{36}+\frac{1}{34} ) } }$

$t = \frac{-1.5}{0.337} = -4.45$

The test statistic | t | = |-4.45| =4.45

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A line passes t

Olenka [21]

We are given a line passes through the point (-2,5). The slope should have been given as well. Assuming that the slope is 2, we can determine the values of x and y for the points A and B.
The formula for the slope is
m = (y2 - y1)/(x2 - x1)
The slope between (-2,5) and A(x,3) is
2 = (3 - 5) / (x - (-2))
Solve for x

Use the same approach for the points (-2,5) and B(-2,y) to solve for y.
